The Orientale is a really nice small hostel we would definetly recommend. We are 4 girls and stayed there for 3 nights, but one of us got sick and they allowed us to stay one night longer.
The location is right next to China Town but quite far from Khao San Road.
We love the cute little rooftop sitting area.
All in all the host is really nice, he gave us a little present and water.
We would come back any time.
